I'm afraid it won't solve the fact that the TG program will not work properly for you, but if you just want to get some planes buzzing around, it should work!
Alternatively, contact Just Flight support and we can get it working properly for you. It is designed to run with FSX Steam Edition and so no reason why it shouldn't. Issues are usually down to older versions of FSX hanging around, although that has been resolved so it may be something else.
